Free-fall F22

(1, 0.1, 0.01)

From Li & Liao (2019)

Free-fall F22 (1, 0.1, 0.01) is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 0.1 : 0.01 that return to their starting positions and velocities every 8.4599 time units, published by Li & Liao (2019). Three bodies released from rest fall together, swing past each other and return to rest exactly where they started. It is unstable (largest Floquet multiplier 10681), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000244 of each other at a top speed of 46.2, line up 26 times a period, and the computed loop closes to 1.2×10⁻²⁴.
